Can't send article image to LinkedIn. Just the text

What are you trying to achieve?

I have a friend who writes his blogs and wants them collated and sent to his linkedIn post, along with the image he has selected for the post.
I am retrieving the blog post with RSS but it doesn’t appear to capture the image.
Any ideas on how to capture the image and put it in the post.
I am able to collate the text and that works fine. Just getting the image is not working and I can’t figure it out.
Thanks in advance.

Steps taken so far

I have tried the scenario: RSS>text parser>HTTP>ChatGPT>LinkedIn Image post.
I’ve watched so many youtube videos, but none help
